Are the shape, size (length, width, height) and distance of space/elevation between the chip pcb of the ihs of the 12, 13, and 14th gen cpus all identical?

Just asking because there’s a contact frame from Thermal grizzly for 12th gen processors and an updated contact frame from them for 13th gen with a slightly different shape. BUT that was a year or so ago and I went to buy another 13th gen frame from them BUT now the frames being sold online say “for intel 13/14th gen instead of mine that says “for intel 13th gen” even thought they APPEAR to be the same exact mold (unlike the 12th gen model) but could I be wrong?
